Different Effects Of Weight Change In Men And Women

As mentioned before, many studies have evaluated how weight changes will affect the voice. However, you may not know that this change is different between men and women.

First, let’s talk about the changes in female voices. When their weight exceeds the average threshold, the hormone testosterone will increase higher, leading to their voices tending to be masculine, or in other words, lower and lower.

In contrast, when the heaviness increases, it will simultaneously increase the production and storage of female hormones or stimulate male hormones in men.

So, this change leads to a significant disparity between female and male hormones in the body and makes their voices softer and thinner.

Can Weight Loss Change Your Voice?

You can change your body measurements.

As you’ve seen before, a weight change, either gain or loss, affects your voice. So weight loss is no exception. Losing heaviness can completely change your voice.

Furthermore, the law of diminishing returns has shown that if you increase the input of one factor while keeping all other factors constant, the corresponding returns will start to slow down.

You may find that losing weight affects your voice when it comes to heavy loss. You see that it is interesting, and you decide to lose weight.

However, the amount of heaviness you lose does not mean changing your voice. In other words, if you’re trying to increase your natural sound output with drastic weight loss, you’re likely to be disappointed.

Meanwhile, for some people who are too thin, their sound systems are more fragile and more prone to injury.

Relationship Of Weight Loss With Acoustic Parameters

According to a study by Lourdes Bernadette on the effect of weight loss with technical parameters, these researchers suggest that patients with obesity will change their voices due to fat accumulation in the vocal tract.

So, they performed a study on obese people after loss surgery and people with the average number. After the study period, the obese people who lost weight after surgery showed that neck circumference, basal frequency, and maximum vocal time were close to the average values ​​of ordinary heavy people.

As such, the acoustic parameters are influenced by weight loss.

Some Other Factors Affect Your Voice

When you speak or sing, the process of creating your voice begins in your lungs. When your lung capacity decreases, your agent will sound weaker. However, several other factors also affect your voice:


2. Genetic


The first is the genetic factor. You will quickly notice that people in the same family often have pretty similar voices due to the larynx structure, which contains sounds with similar designs.


3. Sex


Your gender has a significant influence on your voice. You will quickly notice that the male voice will be lower and more profound, while the female voice will be thinner and higher. In addition, from birth, the vocal cords of boys have developed more than that of girls.


Many studies have shown that tall people often have lower airways and lungs, resulting in lower voices.

Weight and hormones

4. Older men will often increase estrogen production

Older men will often increase estrogen production.


Hormones can affect your voice. Older or obese men will often increase estrogen production, making their voices higher. In contrast, obesity in women increases the male hormone testosterone and makes their voices deeper.

One of the hormone potent effects of loss on voice is puberty in men. Specifically, Testosterone can stretch the vocal cords and dilate the nasopharynx, thereby making the male voice significantly lower than before. The role of estrogen is similar, increasing the frequency of sounds in females.


Essentially, being overweight affects your ability to control your breathing and makes your voice hoarse. On the other hand, when underweight, your vocal cords are also more susceptible to injury, and your voice becomes weaker.

To be more specific, obesity tends to suppress rational function and cause your vocal range to drop significantly compared to the past.
